Abarelix in Prostate Cancer Hormone Therapy

Abarelix a LHRH
antagonist or a GnRH antagonist used for prostate
cancer hormone therapy. LHRH agonists may cause hormone
flare which can be painful or dangerous for advanced
prostate cancer patients with bone
metastasis. The design of abarelix ablates the testosterone
produced in the testicles without hormone flare. Abarelix,
however, can cause severe allergic reaction in about
5 percent of men. Abarelix is usually not recommenced
in the treatment of prostate cancer unless the use of
an agonist is not a viable option for a patient because
of bone metastasis or if a patient insists on the agonist.
